Phra Phong Suphan (Thai : พระผงสุพรรณ) is from Wat Phra Si Rattana Mahathat (Thai : วัดพระศรีรัตนมหาธาตุ) of Suphanburi Province. There were thieves who came to dig under the large stupa in the temple and stole amulets and tablets, some made from gold. So in 1913 Suphanburi governor ordered the formal dig up to uncover the buried amulets. Phra Phong Suphan was among the amulets found.

A Thai Buddha amulet (Thai: พระเครื่อง), often referred to academically as "votive tablet", is a type of Thai Buddhist blessed item. It is used to raise funds to help the temple's operations. A Thai Buddhist monk will give an amulet to Buddhists as a "gift" after they donate money or offerings to the temple.
